I'm changing the oil and filter in my MY04 STI at the weekend.
Can someone please let me know what tool is req'd for the sump plug removal i.e Torx bit, Allen key etc?
Is the filter easily accessible or does half the car have to come apart to get at it.
Thanks

Kevin

 

Any resident experts out there?

 

Haven't done my own yet, but the only bits that need removing is the undertray, which has IIRC 6-8 bolts. The filter is then easily accessable. Not sure about the sump nut, but every car I've ever done has a standard nut.

Do however follow the correct procedure. I'll assume you know it, if not post back.

 

Thanks corradoboy :-)
Yes I'm well aware of the procedure to follow.
By the time I get back home it's pitch black, so I wanted to be as prepared as possible for Saturday ; tools ready and waiting.
I don't want do have to go out at the weekend and buy the req'd spanner/socket etc.

Do anyone know what I need to remove the sump plug?

Kevin

 

dont know about an 04 but the 02 has a standard sump nut its either 17 or 19mm. Cant remember which. And the undertray has 10 and 12mm bolts

 

Please run through the procedure to follow. Hot or cold ?? empty oil sump remove filter, oil new filter rubber re-fit fill with 4.5 litre 10/40 or 5/30 semi synthetic. have I missed anything ?? going for to do change on Saturday -- advise with corrections please

 

I'm planning oil change, plugs and maybe diff oils this weekend too on my sports.

Do a search thru the forum, there's loadsa of procedures in many threads and lots of do's and donts. Lots of excellent advice.

Noticed that an oil filter from subaru was 1/2 the price of that from Halfords. Dont forget a sump plug washer, about 70p from dealers

Good luck

Yes the filter needs to be filled with oil before fitting,This may take several goes to fill right up as the filter soaks the oil up.Then fill the engine with oil,Then disconnect the cranksensor and Crank the car til the oil light goes out,Then reconnect the cranksensor and start the car. After this the engine managment light may be on this take 10 starts until the light goes out.

 

Why do you do this and where is the sensor, I changed the oil in my old Sport and never did owt like this. This is sounding complicated .......Then disconnect the cranksensor and Crank the car til the oil light goes out,Then reconnect the cranksensor and start the car. After this the engine managment light may be on this take 10 starts until the light goes out.

 

This is done to prime the oil system to stop the crank bearings becoming dry when the engine is first started after an oil change. Its very easy to do. there are many threads on it just do a search.The crank sensor is located above and behind the bottom pulley. there is a small eletical plug on it. The reason the managment light come on is because the ecu figures theres a problem as there will not be a signal from the cranksensor. After a few starts normally ten athough it can be less the ecu sees the fault has gone and puts the light out.

 

This is an Urban Myth ...... just do it as the dealers do

Fill with quality oil and START the frigging thing .....

This is my opinion - do as you wish ..... but no car I have ever done has sufferred through just starting right away!

So we know where to send the bill if it all goes *** over tit

On any engine that I've rebuilt, I'd always do the above procedure to ensure there is enough oil pressure available on the all important start up. Whilst this may not be so neccessary on an already run engine, it certainly will do it no harm but may go someway towards prolonging the engines life.
Most people realise the importance of correctly allowing the engine to cool down after a "hard" run and in the same way this also helps.
pslewis, do you thrash your car from cold?

 

Agreed it takes an extra 5 mins to do this and most if not all of the scoob specialist do this. If you dont and it goes wrong DONT sent the bill to me send it to someone that knows better

 

NO I do NOT thrash my car from cold and I do NOT thrash it at ANY other time

If I have been a bit 'spirited' then I allow the engine to cool down for a few minutes

Engine rebuilds are completely different .....

On an Oil Change there is still oil in the bearings, and in most parts of the engine

The Filter SHOULD be filled first ...... but cranking the engine on the starter is IMHO an old wives tale and only one I have heard on SN I have to say!

Do it if it gives you peace of mind, but I don't think your engine will blow up if you don't!

Do SUBARU recommend the cranking procedure? They are the ones who DESIGNED the car, TESTED the car and write the service schedules! (you can bet your bottom dollar that if they thought they could make you pay for a complete waste of 20 minutes extra on a service, then they WOULD!)

Pete
I was not implying that you did thrash your car. What I did mean is that you know that belting a car from cold does it no good, thus cranking the engine over after an oil change to build up some oil pressure can only help.
I'm well aware that there's no chance of it blowing up, but it surely it must go someway in prolonging the engines life.
I intend to keep my STI for a while and if changing the oil before its recommended service interval, which is not neccessary as far as Subaru/I.M are concerned, again helps its health that bit more then it has to be worth it.

Kevin

 

Yes, Kevin - you do what you feel happy with.

I, too, want my car to last for at least 150k miles before it starts to show signs of age - but, I draw the line (personally) at cranking the engine ......... you do know that most wear occurs during cranking?

I have serviced many, many cars over many, many years and have never even been tempted to carry out the cranking procedure - EVER.

Pete

 

pete,

stop talking out of your **** for a change.

there are many bbs users who recommend that you DO disconnect the crank sensor and crank the engine before allowing it to fire.

at least one of these users is an engine rebuild specialist.

but then know it all pete knows best

 

That's your opinion Mr Lewis. Now stop doing the 'troll' thing and frig off!

 

Pete
Yes I know that a lot of wear happens at the engine start up and when it's cold, but I don't know if this is reduced if it is cranking as opposed to the engine starting and firing immediately?
Still I think you'll agree, we both look after our cars even if one of us goes too far

Robocop, this guy voices his unpopular views just to gain some attention. As most of us have already, you will come to think of him as an added comedy bonus!!!

 

and to finally put a nail in the old boys coffin...

read the post by APIDavid amongst others. (and it has a handy step by step guide to the oil change).

 

To be honest I was reading a thread somewhere either here or SIDC, so I already knew of his notoriety shall we say.
